Google Makes Gemini 4 Carbon Widely Available, Follows With Gemini 4 Hydrogen for Everyone
Google announced this week that Gemini 4 Carbon, its strongest super intelligence (SI) model, is now widely available to developers, enterprises, scientists and consumers. The model was first unveiled on October 28 with access limited to cybersecurity defenders and trusted partners, and it reached general availability on November 10.
Google says Carbon's strengths are cybersecurity capabilities and long-horizon agentic workflows, with frontier performance across complex knowledge work, software engineering and scientific reasoning. It is available through the Gemini API in Google AI Studio and Gemini for business, and is rolling out to Google AI Ultra subscribers.
On November 12, Google followed with Gemini 4 Hydrogen, a lighter model in the same generation built for speed and efficiency in everyday coding and agentic workflows. Hydrogen is available to everyone, across Google AI Studio, the Gemini API, the Gemini app and Google Search.
Google also introduced Orchestrator in its Antigravity development tool, which automatically switches between Carbon and Hydrogen within a single session, using the stronger model for hard problems and the lighter one for fast execution.
The Gemini 4 generation now spans Carbon, Argon and Hydrogen: Carbon for the hardest problems, Hydrogen for the speed and cost of everyday work. Google is headquartered in Mountain View, Santa Clara County, California.
